Abstract
A fireplace gas burner unit is provided which allows for excellent aeration and distribution of the combustion gas without excessive gas flow noise. The burner includes a typical open-topped container box with triangular sides. A perforated burner pipe is disposed horizontally within the container box, with the perforations angled slightly towards the front of the box. A deflector plate is attached across the top of the burner pipe and is slanted forward and downwardly to form a narrow slit near the front of the container box. The narrow slit has a long central section and opposing periphery sections. The central section has a greater opening height than the periphery sections.
